Redux Observable: Fire same epic for multiple actions

I want to fire the same contents of my epic in response to several actions. Something like this:

export default function uploadImage(action$, store) {
  return action$.ofType([
      'UPDATE_IMAGE,
      'UPDATE_INTERESTS',
      'UPDATE_LANGUAGE',
      ...
    ])
    .switchMap(action => {
      Api.updateUser();
    })
};

Is this possible?

You're correct in your self-answer, ofType accepts an arbitrary number of types as arguments.

This isn't currently documented because in practice we've found almost always it's a sign of an anti-pattern--not always, but it's highly suspicious.

Until we have solid guidance on when it's good or bad, we want to continue to discourage it's use as a general rule, but certainly only you can be the judge of whether it's appropriate or not.

From the looks of the docs it seems to take an variable amount of arguments: https://github.com/redux-observable/redux-observable/blob/fd393a1adf359381c98ca494bc5dc2cac80f6d07/src/ActionsObservable.js#L26
